My lipid panel indicated very low total cholesterol and even LDLs were lower than my cardiologist was happy with. At the time my Crestor intake of 20mg a day, coupled with 1 gram of Niaspan, and a strict diet and heavy exercise problem lead to these results.

The high reverse t3 levels (rt3) are a result of a restricted diet with over training. To verify there was no issue the reader will note in the results a lab draw on 10/12 that measured Iodine. The link discusses the relationship between Iodine and the thyroid gland.

Very low cholesterol has been tied to issues with memory loss and dementia, as well as other health issues. While many TRT specialists aim for a total cholesterol of 180 mg/dL I believe the body can function with lower levels. The thinking goes something like this. See the hormone tree below:

Note the cleaving enzyme that cleaves cholesterol into pregnenolone and then on down the steroid pathway. Without enough cholesterol there is not enough fuel for the remaining hormonal system, right? True – to a point.

The reality is everyone is different and that 180 mg/dL is not some magic number or target. For some, 120 may work fine, or even lower. The worry is that patients will remain non-compliant with cholesterol lowering medications without doctor supervision in an effort to “jump-start” their own testosterone or maximize hormone fuel by boosting cholesterol. The warning here is…be careful.

I lowered my dose to 5mg of cholesterol and purchased a cholesterol meter that measures Total Cholesterol, Triglycerides (TG), and HDL. This allows LDL to be calculated using the formula LDL Cholesterol = Total Cholesterol – HDL – (TG / 5). I ensure I am always above 120 and I am doing just fine. If I hit 180, I don’t panic. I get by without any problems with frequent exercise and some sanity in my diet.

Not shown in this lab that did show up on previous labs is an increase in hematocrit and RBC leading to polycythemia – an increase in red blood cell count per unit blood volume. This increases the risk of clot formation. If you have heart disease, watch out for this side effect. More often seen on shot therapy for TRT, it can happen even with gels. Treatment usually involves blood letting, a procedure that can be ordered by your doctor. Also, it helps to cease TRT treatment every 12-18 months for a short period of time.

As far as the testosterone levels go, I was on 1.5 tubes of Testim for this test, applied in the morning, and the blood work done 2 hours after application. My testosterone was screaming high at over 1400ng/dl. This level is a false reading as a future lab would indicate.

WARNING: Never apply Testim or any gel to the area where the blood draw will occur. This can taint the results. This is what happened for this particular test. I had to ignore the results.

The next number of posts will contain information from all of the labs that I still possess copies of starting from 5/27/2010 when I first noted my hypogonadism had returned. This occurred after a failed restart, which initially showed promise, before levels returned to pre-post cycle therapy (PCT). The PCT involved HCG, Clomid, and Tamoxifen. The fact I responded to HCG indicated no issues with the testicles in producing testosterone when stimulated, and my response to both Clomid and Tamoxifen after HCG cessation indicated no issue with the hypothalamus or pituitary gland. Coupled with older MRIs from years ago that indicated no growths or other issues with my adrenals and pituitary gland, as well as a full brain MRI, this strongly pointed to neither primary (testicles) or secondary (hypothalamus and pituitary) hypogonadism, but rather hypogandism that was idiopathic in origin.

It was at this time, years ago after a collapse following treatment with a combination thiazide diuretic and ACE inhibitor for blood pressure, that I first started testosterone replacement therapy (TRT). After the PCT fail, I restarted TRT and began working with my family physician. The initial results that indicated low testosterone follow. However, it should be noted that a body mass index done a couple of months later indicated large adipose fat deposits, and previous labs pointed to insulin resistance. At the time, I did not understand the significance of this finding. My body fat from the hydrostatic chamber test hovered around 27%. With insulin resistance, SHBG tends to be low. Recall the formula: Free T = Total T – SHBG bound T – Albumin bound T. As testosterone is easily ripped off of Albumin, Bioavailable T is basically Free T + Albumin bound T.

First I must divorce any misconception this is the first flirtation with TRT. About 8 years ago, after taking the blood pressure medication Prinzide – a combination Thiazide diuretic/ACE inhibitor – I had a collapse after four days. Profound in nature, this event changed my life. From a strapping young man capable of 100 push-ups, I could not longer manage even 10. A visit to a local endocrinologist indicated all of my endocrine systems were compromised. Suddenly I was diabetic, I became seriously depressed, and all of my muscles experienced a weakness that was frightening. This included my diaphragm and I required a velcro weight belt to provide support and assist in relieving any weight on the diaphragm just so I could breathe.

I immediately began to treat the depression, and began an exercise program that consisted of 100 deep-knee bends, as many push-ups as I could handle, and walking for short distances. After the depression resolved itself, additional tests which indicated high cortisol and I barely passed a dexamethasone supression test. Failure of this test is indicative of adrenal issues. Measured testosterone was very low at 185 ng/dL. I decided to treat the testosterone only and attempted both Androgel and Testim, finally deciding on the Testim. I saw many specialists including a neurologist, a lung specialist, a neurosurgeon, and a cardiologist. After over fifty thousand dollars worth of tests they found….nothing wrong. MRIs, stress tests, multiple visits to my general practitioner and nothing, nada, zilch. I first suspected rhabdomyolysis, which testing quickly ruled out. MRIs of the pituitary, hypothalamus, and adrenals were negative. The only conclusion offered by one doctor – I suffered from a variant of Guillain-Barre syndrome, an ascending paralysis that in the worse cases becomes complete, with the patient on a ventilator. The disease usually resolves itself after a period of months, weeks, and sometimes years.

So just how does the male body produce testosterone? While the number of systems that can impact testosterone production is large in number, the basics are rather simple. Let’s start at the hypothalamus and work our way down.

The hypothalamus produces gonadotropin-releasing hormone (GnRH)

This hormone triggers the anterior pituitary gland to produce two other hormones

These two hormones are luteinizing hormone (LH) and follicle-stimulating hormone (FSH)

LH stimulates the Leydig cells in the testicles to produce testosterone while FSH regulates the development, growth, pubertal maturation, and reproductive processes of the body and acts synergistically with LH in male reproductive health.

Simple enough, but what happens is one or more of these systems is compromised in some manner? Defects in the hypothalamus or pituitary gland that compromise the release of GnRH (and subsequently FSH and LH) or adversely affect the release of FSH or LH from the anterior pituitary lead to what is known as secondary hypogonadism. A defect in the testicles that causes a reduction or cessation of gonadal response to LH is characterized as primary hypogonadism. There are many causes of both primary and secondary hypogonadism. The link lists only some of the causes. Also check out this link. Hypogonadism that is present absent any of these conditions or any other known conditions that affect male testosterone production comes under the heading idiopathic hypogonadism. This later label correctly describes my own condition.

Typically a doctor will order a test that measures the total serum testosterone. This is a simple blood test that provides a number, usually in the units of nanograms per deciliter (ng/dl). Normal values vary by the lab performing the test on the blood sample, but typically values are from around 300ng/dL to 1000ng/dl. However, caution should be used in using this raw value as an stark indicator of hypogonadism. For some men presenting with low normal values or even normal values symptoms of low testosterone are often seen. Therefore the entire clinical picture is needed to ensure treatment is provided even in the face of so-called normal results. Also, an entire workup of the thyroid function as well as adrenal function is necessary. Any issue with either of these glands can often lead to hypogonadism or mimic they symptoms of hypogonadism. Also, an understanding of any issues with these glands will guide the treating physician in the selected treatment. As an example, long-standing hypothyroidism will impair the absorption of transdermal testosterone due to build-up of mucin in the skin of people. Mucin causes the skin to thicken impairing absorption of transdermal testosterone.

This is a topic dear to my heart. I need to add to my story the fact that I am hypogonadal and my hypogonadism (low testosterone) is addressed with Testim, a gel I rub on my shoulders in the morning. When I stopped using the Testim, my testosterone is slowly recovering.

However, in an effort to “jump start” my testosterone production my primary doctor, in concert with an expert in Houston, is prepared to start me on HCG (human chrorionic hormone), Nolvadex, and Clomid. Not to get too technical, but HCG acts like luteinizing hormone (LH) which stimulates the testicles to generate testosterone. Nolvadex and Clomid are anti-estogens, and Nolvadex’s extra benefit of making the pituitary gland more sensitive to GnRH is an added bonus. GnRH (Gonadotropin Releasing Hormone) is a hormone release by the hypothalamus to the pituitary gland, resulting in the gland releasing LH to the testicles, which in turn create more testosterone.

If all goes well, normalization for me should occur within 1-3 months, instead of 12 months or more. However, in two weeks I will know whether my testicles are capable of producing the needed testosterone from their response to the HCG injections. If normalization does not occur, I will be back on the Testim.

This brings me to the main point of this post. Is heart disease caused by low testosterone, or visa versa? Here is an excellent interview with Hugh Jones, MD on the subject. This is an area just screaming for more study. Also, to my knowledge no study of the effects of testosterone on endothelial coverage of a stent has been done. Some snippets from the article:
